Discrete Fundamental Solution Preconditioning for Hyperbolic Systems of PDE
We present a new preconditioner for the iterative solution of linear systems of equations arising from discretizations of systems of first order partial differential equations (P...

On the semigroup of linearized forced elongation
In this note we analyze the linearized equations of forced elongation. We prove that solutions of these equations are given by a quasicontraction C0-semigroup on the physically co...

Hamiltonian restriction of Vlasov equations to rotating isopycnic and isentropic two-layer equations
A direct link between a Vlasov equation and the equations of motion of a rotating fluid with an effective pressure depending only on a pseudo-density is illustrated. In this direc...

Equations in Free Inverse Monoids
It is known that the problem of determining consistency of a finite system of equations in a free group or a free monoid is decidable, but the corresponding problem for systems o...

Absolute Stability and Complete Synchronization in a Class of Neural Fields Models
Neural fields are an interesting option for modelling macroscopic parts of the cortex involving several populations of neurons, like cortical areas. Two classes of neural field equ...

On the hardness of approximating Max-Satisfy
Max-Satisfy is the problem of finding an assignment that satisfies the maximum number of equations in a system of linear equations over Q. We prove that unless NPBPP Max-Satisfy c...
